What flat roof work do we do in Huyton?

Extension and kitchen roofs

Rooflights fitted after the roof was built are a frequent source of trouble in Huyton extensions. If the kerb was not formed properly or the membrane was simply sealed around the frame, leaks follow. Replacing the roof is the chance to rebuild every upstand to a proper standard.

Single-ply membrane roofing

Single-ply is a common choice for medium and large flat roofs in Huyton because it covers big areas quickly, is light on the structure and has a long typical life. Wide rolls mean fewer seams, and those seams are welded and probed rather than glued.

Garage roofs

Many garages in Huyton still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.

What flat roofs are typical in and around Huyton?

In a large town like Huyton flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and shops with flat-roofed rear stores below flats. Weather matters on a flat roof. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to Knowsley Council building control, or a registered building control approver.
